Below is the error I get.
<In what way does your code behave incorrectly? Include ALL error messages.>
“Oops, try again. get_class_average([alice]) resulted in an error: ‘tuple’ object has no attribute ‘append’”
<What do you expect to happen instead?>
Problem occurs with the get_class_average function.

```python

lloyd = {
“name”: “Lloyd”,
“homework”: [90.0, 97.0, 75.0, 92.0],
“quizzes”: [88.0, 40.0, 94.0],
“tests”: [75.0, 90.0]
}
alice = {
“name”: “Alice”,
“homework”: [100.0, 92.0, 98.0, 100.0],
“quizzes”: [82.0, 83.0, 91.0],
“tests”: [89.0, 97.0]
}
tyler = {
“name”: “Tyler”,
“homework”: [0.0, 87.0, 75.0, 22.0],
“quizzes”: [0.0, 75.0, 78.0],
“tests”: [100.0, 100.0]
}

def average(numbers):
total = sum(numbers)
total = float(total)
total = total/len(numbers)
return total
def get_average(student):
homework = float(average(student[“homework”]))
quizzes = float(average(student[“quizzes”]))
tests = float(average(student[“tests”]))
return 0.1homework + 0.3quizzes + 0.6*tests
def get_letter_grade(score):
if score >= 90:
return “A”
elif score >= 80:
return “B”
elif score >= 70:
return “C”
elif score >= 60:
return “D”
else:
return “F”
students = [lloyd, alice, tyler]
def get_class_average(students):
results = ,
for student in students:
results.append(get_average(student))
return average(results)

Add your function below!

@micah.edelblut,
Remove the comma-,
from

results = []

in your get_class_average function.
